"Is this the location of metal attribute treasure, the black gold essence?"
Lin Lee muttered thoughtfully, looking at the huge underground dark space.
After venturing deep inside the sand swirl, he landed in this strange underground ruin.
Lin Lee glanced at the dark walls around him without any rust and dust, a lot of engravings, and different mechanisms of holes-like structures from which the sand is flowing below; also, the whole structure looks like it is made from metal.
Lin Lee appeared beside the wall and tapped it; instantly a cold metallic sensation passed through his finger, and a clanging sound spread toward the surrounding
"It's indeed metal," Lin Lee nodded and muttered thoughtfully and then walked forward toward the middle of this underground area, although this place has a special structure and mechanism, but it's small, just the size of a football field.
